Pileus firm, convex or slightly depressed in the center, smooth, pale-gray ; 

 lamellae moderately close, adnate or slightly decurrent, grayish, then flesh- 

 colored ; stem solid, colored like the pileus ; spores angular, irregular, 

 .0004 -.0005 long, .0003' broad ; odor farinaceous. 



Plant 2-3' high, pileus 6 -12 " broad, stem l"-2" thick. 



Ground in woods. Adirondack Mountains. Aug. 



Agaricus (Clitopilus) micropus Pk. 



Pileus thin, fragile, convex or centrally depressed, umbilicate, silky, gray, 

 usually with one or two narrow zones on the margin ; lamellae narrow, close, 

 adnate or slightly decurrent, gray ; stem short, solid, slightly thickened at 

 the top, gray, pruinose, with white mycelium at the base ; spores angular,

Plant 1 high, pileus 6' '-12" broad. 



Ground under trees. Ticonderoga. Aug. 



Agaricus (Leptonia) undulatellus Pk. 



Pileus membranaceous, convex, minutely scurfy, squamulose on the disk, 

 hygrophanous, grayish-brown and striatulate when moist, wavy on the margin ; 

 lamellae rounded behind, nearly free, subdistant, whitish, then tinged with 

 flesh-color ; stem slender, glabrous, colored like the pileus, usually curved ; 

 spores irregular, .0004 long, .0003' broad. 



Plant about 1' high, pileus 6 -8" broad. 



Decaying prostrate trunks of trees. Pine Hill. Sept. 



When dry, the pileus is somewhat shining, and the disk a little darker. 



Agaricus rhodocaltx Lasch. 



Ground in woods. Adirondack Mountains. Aug. 



Agaricus (Pholiota) squarrosoides Pk. 



Pileus firm, convex, viscid when moist, at first densely covered by erect 

 papillose or subspinose tawny scales, which soon separate from each other, re- 

 vealing the whitish color and viscid character of the pileus ; lamellae close, 

 emarginate, at first whitish, then pallid or dull cinnamon color ; stem equal, 

 firm, stuffed, rough with thick squarrose scales, white above the thick floccose 

 annulus, pallid or tawny below ; spores minute, elliptical, .0002' long, .00015' 

 broad. 



Densely caespitose, 3-6' high, pileus 2-4' broad, stem 3 "-5" thick. 



Dead trunks and old stumps of maple. Adirondack and Catskill Moun- 

 tains. Autumn. 



This is evidently closely related to A. squarrosus, with which it has, per- 

 haps, been confused, but its different colors and viscid pileus appear to war- 

 rant its separation. 



Agaricus (Pholiota) limonellus Pk. 



Pileus thin, convex or expanded, subumbonate, viscid, rough with scattered 



erect reddish-brown scales, lemon-yellow; lamellae narrow, close, rounded
